'. IMPROVEMENT IN RAILWAY SWITCHES.

Specification forming part'of Letters Patent No. 124,719, dated March19, 1872.

Specification describing a new and Improved Railroad SWitchChair andRod, invented by PATRICK GARRIGAN, of Sturgeon, in the county of Booneand State of Missouri.

Figure 1 is a detail cross-section of my improved railroad switch takenthrough the line :v x, Fig. 2. Fig. 2 is a top viewof the same.

Similar letters of refe-rence indicate corresponding parts.

My invention has for its object to improve the construction of railroadswitches in such a way as to cause the rails to be securely held inplace when adj usted, and so that the weight of the sliding or movablerails will bring them exactly in line with the stationary rails shouldthey be moved by the switch-rod a little too far or not quite far enough5 and it consists mainly in providing V- shaped recesses on therail-chair and switch-rod, as hereinafter described. Y

A are the movable rails. B are the stationary rails of various tracks,with any desirable set of which the movable rails Amay be adjusted toconnect, as may be desired, and which are inserted in sockets c formedupon the upp'er part of the switch-chair C. C is the switchchair i*block, whichis grooved to receive the switch-rod D.- The switch-rod Dmay be made jointed, as shown in Figs. 1, 2, and 3, or rigid, as may bedesired. The outer end of the switch-rod D is pivoted to the lower endof the switchdever E, which is pivoted to the stand F in the ordinarymanner. Upon the upper side of the rod D are formed sockets or chairs toreceive the ends of the movable rails A. Upon the under side of the rodD are formed V-shaped projections Gr, which enter V-sha-ped recesses Hin the bottom of the groove in the chair or block C, in which the saidrod works. Upon the upper side of the chair G are formed V-shapedprojections I, in

such positions as to be at the sides of the movable rails A whenadjusted to connect with either set of the rails B. The projections Grand I, or either of them, hold the rails securely in place whenadjusted, and, at the same time, the inclined sides of said projectionscause the rails A to slide into line with the stationary rails B shouldthey be moved a little too far or not quite far enough by the lever E.

My invention thus differs materially from those in which the ends of therails fxtin sockets formed with straight sides, since, in the lattercase, the rails will not enter the sockets unless a very perfectadjustment be first effected by the operation of the switch-rod andlever.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. The V-shaped projections G formed upon the underside of the switch-rod D, and operating in connection with the V-shapedrecesses H formed in the bottom of the groove in the 11i y l PATRICK -lCARRIGAN.
